To all whom it may concern: 7

Be it known that I, DANIEL A. HAAS, a

citizen of the United States, residing at Belleville, in the county of St. Clair. and State of Illinois, have invented. certain new and useful Improvements in Shocker Attachments for Binders, of which the following is a specification.

This invention relates to shocker attach ments for binders, and has for its primary object to provide a shocker of simplified and improved construction which is capable of being readily applied to or detached from binders of that type now in use.

A further object of the invention is to provide a shocker of the character mentioned which normally remains in position to receive a bundle or shock, but which may be quickly and easily actuated to dump the bundle and after performing this function, the said shocker automatically returns to normal or bundle-receiving position.

Still further objects reside in providing a shocker of the type mentioned, which is composed of but few readily assembled parts, which has its various parts so assembled as to minimize the opportunity for wear or breakage,'which derives its operating power-from the power mechanism upon the binder, and which will prove thoroughly efiicient in practice. I

With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts all as will be described more fully hereinafter, illustrated in the drawings and particularly pointed out in the claims.

In the drawings: I

Fig. 2 is an end view of the device illustrated in Fig. 1, a

Fig. 4 is a longitudinal sectional view taken through a portion of the shocker bar, Fig. 5 is an end elevation of the rotatable member which is employed for operating the shocker bar, and

Fig.6 is a sectional view taken through the'housing for the rotatable member, and

the improved illustrating the mechanism for throwing the shocker bar into operation.

In carrying out the invention, use is made of a frame of relatively small dimension which is applied to the binder adjacent the bull or power wheel thereof. This frame is indicated generally at 5, and includes a pair of spaced parallel bars 6 and 7, rigidly secured to the end bars 8, the latter being secured at their inner ends to the frame or body of the binder. This improved frame also includes a supporting bar or rod 9, disposed in spaced parallel relation to the bars 6 and 7, but projecting outwardly beyond the body or frame of the binder.

Mounted for rotation in a suitable bearing 10 secured between the bars 6 and 7 intermediate the ends of the latter, is a jack shaft 11, to one end of which is secured a sprocket wheel 12, over which passes a chain 13. This chain in turn passes over a sprocket let upon the binder, and which may be driven in any suitable manner from the power wheel, or from a power mechanism located upon the binder. The outer end of the shaft 11 is equipped with a disk 15, which will be referred to hereinafter as the rotatable .member. This disk is housed within a casing 16, the latter being secured in any preferred manner to the frame 5, and it will be observed that the outer end of this casing is open. The disk 15 is provided in its periphery with spaced teeth indicated at 17, which teeth are adapted to engage and deliver a rotary and oscillatory movement to the shocker bar to be hereinafter detailed.

' The shooker-bar is indicated generally at 18, and is pivoted intermediate its ends as at 19, to the supporting bar or rod 9. The outer end of this'shocker bar carries a shock holder indicated generally at 20, and Within which the bundles are adapted to be dropped. This shock holder may be of any approved construction, and when the shocker bar is in normal position, this holder is disposed so as to receive and support a bundle or shock delivered thereto from above. The bar 18 may be hollow throughout its entire length, and a pin 21 is slidably arranged within the inner end of said bar, being held against rotary movement therein by a tie bolt or pin 22, and the said pin also serves to limit the longitudinal sliding movement of the shaft pin 21. The outer extremity of the pin 21 is equipped with a head 23,

' the latter extending within the disk inclosing casing 16. It will be observed that the open end of the casing 16' is provided with an inwardly extending flange 24L, behind which the head 23 engages, and it is obvious from this construction that the pin will be prevented from becoming disengaged from the interior of the housing. The casing 16 is offset as at 25, so that when the pin 21 is disposed within the offset portion, the said pin will be out of the course of travel of the teeth17 upon the periphery of the disk or rotatable member 15. It is obvious, therefore, that when the shocker bar is in such position that the pin 21 carried thereby will be disposed within the ofiset portion, rotary movement of the disk 15 can in no way affeet the said shocker bar. A guide plate 40 is arranged in the housing in the path of travel of roller 23, so as to cause the latter to move into the offset 25 once in each revolution of the arm.

Arranged within the annular wallof the casing 16 and adjacent the offset portion 25 thereof is a movable leaf 26, which is adapted when moved inwardly to engage with the pin 21 and to force the same out of the offset portion and into the path of travel of the teeth in the periphery of the disk 15. Said leaf is hinged as shown, and a lever 27' operated by a rod or cord 28 is adapted to rock the said leaf into operative position. A suitable spring may be employed for returning these parts to normal position after pressure upon the rod or cord 28 has been released. I

Rigidly secured to the shocker bar 18 and adj acentthe inner end thereof is an arm 29. Ihis arm extends downwardly as shown, and is connected at its free end with the frame 5 by a link or rod 30. It is apparent from this construction that rotary movement delivered to the inner end of the shocker rod or bar will be limited, and as the disk 15 rotates, the said bar will be partially rotated .and operated. To permit of this peculiar movement of the shocker'bar, the pivot arrangement of the shocker bar consists of a pair of clevises 31 and 32, pivoted together as shown, the former of which is connected loosely to the shocker bar, while the latter is secured to the bar or rod 9. It will be observed that the first mentioned" of these clevises is disposed between a pairof collars 33 aflixed to the shocker bar.

As has been before stated, when the shocker bar has its inner end disposed within the offset portion of the casing 16, the shock received at the outer end of the bar is disposed with its tines or teeth substantially parallel to the ground, so as to retain a shock or bundle delivered thereto. When it is desired to deposit this bundle, the cord or rod 28 is pulled, whereupon the bellcrank lever 27 depresses the leaf 26, thus forcing the inner end of the shocker rod downwardly into the path of travel of the teeth on the disk 15. One of the said teeth thereupon engages the pin 21, and carries the latter around the casing. This movement of the inner end of the shocker rod causes the outer end of the said rod first to move rearwardly and then downwardly, and as the inner end of the said bar continues to move, the link or rod 30 secured to the arm 29 will limit the rotation of the said shockerbar, and after-the inner end of the said bar reaches the lowermost extent, of its movement and starts traveling upwardly, the said bar will rotate, so that the shock holder will be inverted. This part oscillatory and part rotary movement of the shocker bar causes the holder at the outer end thereof to become inverted, and as the binder'passes over the ground, the teeth or tines of the said holder will pass over the upper end of the shock which has been deposited upon the ground. As soon as the inner end of the shocker bar again enters the offset portion, the shock holder at the outer end thereof will have resumed normal position, and is ready to receive more bundles or shocks.

From the foregoing, it will be obvious that I have provided an extremely simple and yet thoroughly eflicient shocker attachment for use upon binders, and one in which the mechanical operations are performed automatically after once the mechanism has been set into operation.

While the present is a disclosure of the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, as various changes in the minor details of construction, proportion, and arrangement of parts may be resorted to if desired without departing'from the spirit of the invention as defined-by the appended claims.
